Small osmosis damage may be repaired with Epoxy Repair.  

Osmoshell is a solvent-free epoxy coating, reinforced with glass flakes, giving a very high structural surface, being virtually waterproof. This is a curative coating system for hulls affected by osmosis.  
(*) If abrasive material cannot be used, coarse sanding with P40 – P80 dry paper is recommended in order to ensure the correct surface roughness and full adherence of the system.  
(**) Finishing Filler is recommended to obtain a smooth surface, as Osmoshell will leave certain roughness after application and should not be sanded to avoid film thickness reduction. Finishing Filler can be easily sanded to get a smooth surface.  
Moisture content of the hull has to be less than 1% before application of any coating.
